Abstract

The invention relates to a cosmetic mask, particularly to a cosmetic mask that is a water insoluble substrate with a composition impregnated therein which can be applied to the face or any other topical surface of the body. The cosmetic mask provides both the benefits of a skin care active that delivers long-term benefits as well as instant lightening benefits without the disadvantages of unnatural whiteness that is often associated with such instant lightening products.

First claim

1 . A cosmetic mask comprising a water insoluble porous substrate impregnated with
(i) a skin care active selected from retinol, retinyl esters, resorcinol, vitamin B3, allantoin, ubiquinone, conjugated linoleic acid, 12-hydroxystearic acid or derivatives of resorcinol and vitamin B3, wherein said resorcinol derivative is a 4-substituted resorcinol and wherein said vitamin B3 derivative includes niacin, nicotinic acid, and/or niacinamide; (ii) a skin whitening particle selected from polymeric beads, boron nitride, or mica; and (iii) a film-forming polymer.

2 . The cosmetic mask as claimed in claim 1 wherein said water insoluble porous substrate is selected from paper, polymeric web, fabric, or composites/mixtures thereof.

3 . The cosmetic mask as claimed in claim 1 or 2 wherein said polymeric bead is a hollow sphere made of a styrene/acrylate co-polymer.

4 . The cosmetic mask as claimed in claim 1 wherein said skin care active is a resorcinol, vitamin B3, conjugated linoleic acid, 12-hydroxystearic acid or a derivative thereof.

5 . (canceled)

6 . The cosmetic mask as claimed in claim 1 wherein said 4-substituted resorcinol includes 4-ethyl resorcinol, 4-hexyl resorcinol, 4-butyl resorcinol and/or 4-phenethyl resorcinol.

7 . The cosmetic mask as claimed in claim 1 wherein said skin care active is present in 0.001 to 5% by weight of the cosmetic mask.

8 . The cosmetic mask as claimed in claim 1 wherein the whitening particle is present in 0.1 to 5.0% by weight of the cosmetic mask.

9 . The cosmetic mask as claimed in claim 1 wherein the whitening particle has a particle size from 80 nm to 20 microns.

10 . The cosmetic mask as claimed in claim 1 wherein said film forming polymer is selected from an acrylate polymer, a methacrylate polymer, a urethane polymer or co-polymers thereof.

11 . The cosmetic mask as claimed in claim 10 wherein said polymer is an acrylate copolymer or a polyurethane-methylmethacrylate co-polymer.

12 . The cosmetic mask as claimed in claim 1 comprising 0.1 to 15% film forming polymer by weight of the cosmetic mask.

13 . The cosmetic mask as claimed in claim 1 further comprising 80 to 95% water by weight of the mask.

14 . The method of lightening skin comprising the steps of:
(i) applying the cosmetic mask as claimed in claim 1 on to a skin surface for at least one minute; (ii) removing the cosmetic mask from said surface; and (iii) rinsing said surface with water.

15 . The method as claimed in claim 14 wherein said step (iii) is carried out from 0 to 60 minutes after step (ii).
